DUMPlNG-WAGON EPECIPICATION forming part of Letters Patent No. 367,103,dated July 26, 1887;

Application filed January 31, i887. Serial No. 226,074. (No model.)

and Lows NAPOLEON BERGERON, citizens of the United States, residing inStillwater, in the county of Washington and State of Minnesota, haveinvented certain Improvements in Dumping-YVagons; andwe do herebydeclare that the following'is a full andexact description of the same,reference being had to the accompanying drawings, making part of thisspecification.

Our invention consists incertain improvements in the dumping mechanismof a wagon or cart; in the peculiar means by which the wagon or cartbody is held upon the supporting-frame of the running-gear, add in theconstruction ofthe tracks on the said supportingframe, on which theWagon or cart body slides in dumping. These improvements will befullyset forth and defined in the following description and claims. v

In the accompanying drawings, Figure 1 represents a central longitudinalvertical section of a dumpingwagon provided with our improvements; Fig.2, a top view of the runhing-gear and frame of the wagon, the Wagon bodybeing removed, except the hinged connection thereof with the endlesschain by which the said wagon-body is moved backward and forwardindumping; Fig. 3, a view of the under side of the wagon-body, showingalso the endless chains in place in connection therewith; Fig. 4, a rearview of the wagon, the wagon-body being in cross-section in a planecuttingjust at the rear of the runninggear frame; Fig. 5, a partialvertical section on an enlarged scale of the wagon around the tiltingcenter of the body, showing the body in a tilting position.

Like letters designate corresponding parts in all of the figures.

In the drawings, A represents the .wagonbody 5 B, the frame of therunning-gear; O C

, the front wheels, and D D the hind wheels, of

the wagon.

Upon the side timbers, a a, of the supporting-frame B of the wagon twometallic tracks,

' E E, are secured, on which two counter metallic strips, F F, on thebottom of the wagonbody A respectively slide, to take the wear andreduce the friction incident to the backward and forward slidingmovements of the wagon-body in dumping. There is nothing special in theconstruction of these parts, ex-

cept that the steel or iron straps which form the tracks E E are bentaround the rear rounded ends, I) b, of the side timbers, a a, of theframe, on which rounded parts of'the tracksthe wagon-body turns andslidesalittle in tilting; and the said track-straps are extended forwardunder the said side timbers and embrace the ends 0 cof the bolsterG,which rests on the hind axle, H, of the wagomand thence forward andupward to the said side timbers, to which they are respectively boltedat d. These track-strapsthus fulfill the ad-' ditional purpose of bracesfor uniting the bolster to the frame and rendering its connection strongand firm.

For operating the wagon-body, in dumping the same, and returningit toposition after its contents shall have been discharged, we employ one ormore, preferably two, endless chains,l I, in connection withsprocketwheels or simple wheels J J on a shaft, K, mounted in the frameB in a proper position forward of the middle line of the wagon-body whenin preferably the forward shaft, K, in one or the other direction. Thismay be effected by eX- tending one end of the shaft beyond the frame andattaching a winch or crank wheel thereto. But in order to gain leverage,so as to move the wagon-body more easily, it is best to gear the shaft11"] to another parallel shaft, N, mounted in the frame, by the propergearwheels, f g, to give the desired relative speeds to the two shafts,and attaching a winch or crank,0,to the shaft N, as shown in thedrawings. The endless chains 1 I are connected with the wagon-body A forimparting the movement thereto by means of shackle-links or swinginghingesl P,piv0ted to a cross-bar,

11, under the floor of the wagon-body, and also pivoted, respectively,to links of the endless chains, substantially as shownin the drawings.Thus the shackle-links adapt themselves to the proper inclined positionsin whichever direction the chains are moving, so as to draw on thewagonbody without strain in either direction. A feature of value in theconstruction and arrangement of this operating mechanism is that thechains and sprocket-wheels are arranged near the middle of therunninggear frame, one on one side and the other on the other side ofthe center, whereby the weight thereof is kept from leaning, to eitherside,but perfectly balanced or equalized on both sides of the wagon.

For holding the wagon-body on thesupporting-frame at all times, whetherthebody is up right or tilted, and yet not to interfere with the slidingand tilting movements of the body in dumping, we employ two guide-armsor dogs,It It, pivoted upon the rearsproclcetwheel shaft, M, andrespectively reaching up and holding overthe upper sides of longitudinalbars, j j, under the bottom of the wagonbody, near the sides thereof,The outwardlyprqleeting flanges of the guidearms are of considerablelength, as shown, to rest on the said longitudinal bars of thewagonbody, and thus hold securely upon the said bars without muchfriction; and the arms turning on the sprocket-shaft M, which isconcentric with the tilting motion of the wagon-body, hold the saidwagon-body on the frame as well when it is tilted as when itisupright.Suitable washers, It: 1;, if necessary, are placed on the shaft Mbetween the arms R- R and sprocket-wheels L L, to keep them separatedand retain the arms in proper position.

A suitable hook, Z, attached to the front part of the frame B under thedrivers seat S, hooking into an eye, m, on the front end of thewagon-liiody, serves to hold the said wagonbody securely in place. Anyequivalent means may be employed.

\Ve claim as our invention 1. The tracks E E, in con'tbiuation with theside timbers, a a, having rounded rear ends, and the bolster G, the saidtracks being bent around the rounded rear ends of the said tim bers andserving as braces for the bolster, snhsiantially as herein set forth.

2. The combination, with the tiltingwagonbody A and rnnning gear frame13, of the endless chains I I, coupled to thewagon-body,

s n'ocket wheels J J and L L, and shafts K M, substantially as and forthe purpose herein specified.

3. The combination of the wagon-body A, endless chains I I, and swinginghinges l P, pivoted to the said wagon-body and chains, snbstantialiy asand for the purpose herein set forth.

4. The pivoted guide'arms R It, in combination with the wagon body Aandsproeketwheel shaft M of the frame B, substan tially as and for thepurpose herein set forth.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
